These reactions increase the probability of incomplete combustion and are more likely to release uncombusted and photochemically active hydrocarbon compounds into the atmosphere.
这些反应增加了不完全燃烧的可能性，更有可能释放未燃尽和光化学活性碳氢化合物到大气中。
2
Active control of combustion instability is tested on a cold model.
首先，完成了燃烧不稳定性主动控制的冷态实验研究。
3
The content of active aluminum in the combustion residue was determined by means of the titration.
